LONG-TERM DEBT	LONG-TERM DEBT On July 27, 2021, the Company amended and extended its existing credit facility (as amended, the Second Amended and Restated Credit Agreement), which provided for a five-year, $800.0 million senior secured revolving credit facility, including a letter of credit sub-facility of up to $75.0 million. The commitments under the Second Amended and Restated Credit Agreement were set to expire on July 27, 2026, and any outstanding loans were due on that date. On May 13, 2024, the Company repaid $25.0 million of borrowings under the Second Amended and Restated Credit Agreement. On October 4, 2024, the Company amended and restated the Second Amended and Restated Credit Agreement (as amended and restated, the Third Amended and Restated Credit Agreement) with a syndicate of lenders by and among: the Company, as borrower; certain subsidiaries of NetScout Systems, Inc., as borrower; JPMorgan Chase Bank, N.A., as administrative agent and collateral agent; JPMorgan Chase Bank, N.A., Bank of America, N.A., RBC Capital Markets, PNC Capital Markets LLC and Mizuho Bank, Ltd, as joint lead arrangers and joint bookrunners; TD Bank, N.A. and Silicon Valley Bank, a division of First-Citizens Bank & Trust Company, as co-documentation agents; and the lenders and issuing banks party thereto. The Third Amended and Restated Credit Agreement provides for a new five-year, $600.0 million senior secured revolving credit facility, including a letter of credit sub-facility of up to $75.0 million. The Company may elect to use the amended credit facility for working capital and other general corporate purposes (including to refinance revolving loans outstanding under the Second Amended and Restated Credit Agreement and to repurchase of shares of the Company's common stock). The commitments under the Third Amended and Restated Credit Agreement will expire on October 4, 2029, and any outstanding loans will be due on that date. In connection with the Third Amended and Restated Credit Agreement, the Company paid off the outstanding balance of $75.0 million under the Second Amended and Restated Credit Agreement on October 4, 2024 by borrowing the same amount under the Third Amended and Restated Credit Agreement. Additionally, the Company recorded a loss on the extinguishment of debt of $1.1 million, representing the write off of unamortized deferred financing costs, which was included in interest expense in the consolidated statements of operations for the three and nine months ended December 31, 2024. At December 31, 2024, $75.0 million was outstanding under the Third Amended and Restated Credit Agreement. On February 3, 2025, the Company paid the outstanding balance of $75.0 million in full under the Third Amended and Restated Credit Agreement. At the Company's election, revolving loans under the Third Amended and Restated Credit Agreement bear interest at either (a) a term SOFR rate plus a credit spread adjustment of 0.10% or (b) an Alternate Base Rate (defined in a customary manner), in each case plus an applicable margin. For the initial period until the Company has delivered financial statements for the quarter ended December 31, 2024, the applicable margin will be 1.00% per annum for term SOFR loans and 0% per annum for Alternate Base Rate loans, and thereafter the applicable margin will vary depending on the Company's consolidated gross leverage ratio, ranging from 1.00% per annum for Alternate Base Rate loans and 2.00% per annum for term SOFR loans if the Company's consolidated gross leverage ratio is greater than 3.50 to 1.00, down to 0% per annum for Alternate Base Rate loans and 1.00% per annum for term SOFR loans if the Company's consolidated gross leverage ratio is equal to or less than 1.50 to 1.00. The Company's consolidated gross leverage ratio is the ratio of its consolidated total debt compared to its consolidated EBITDA as defined in the Third Amended and Restated Credit Agreement (consolidated adjusted EBITDA). Consolidated adjusted EBITDA includes certain adjustments, including, without limitation, adjustments relating to extraordinary, unusual or non-recurring charges, certain restructuring charges, non-cash charges, certain transaction costs and expenses and certain pro forma adjustments in connection with material acquisitions and dispositions, all as set forth in detail in the Third Amended and Restated Credit Agreement. Commitment fees will accrue on the daily unused amount of the credit facility. For the initial period until the Company has delivered financial statements for the quarter ended December 31, 2024, the commitment fee will be 0.15% per annum, and thereafter the commitment fee will vary depending on the Company's consolidated gross leverage ratio, ranging from 0.30% per annum if the Company's consolidated gross leverage ratio is greater than 3.50 to 1.00, down to 0.15% per annum if the Company's consolidated gross leverage ratio is equal to or less than 1.50 to 1.00. Letter of credit participation fees are payable to each lender providing the letter of credit sub-facility on the amount of such lender's letter of credit exposure, during the period from the closing date of the Third Amended and Restated Credit Agreement to, but excluding, the date which is the later of (i) the date on which such lender's commitment terminates or (ii) the date on which such lender ceases to have any letter of credit exposure, at a rate per annum equal to the applicable margin for term SOFR loans. Additionally, the Company will pay a fronting fee to each issuing bank in amounts to be agreed to between the Company and the applicable issuing bank. Interest on Alternate Base Rate loans is payable at the end of each calendar quarter. Interest on term SOFR loans is payable at the end of each interest rate period or at the end of each three-month interval within an interest rate period if the period is longer than three months. The Company may also prepay loans under the Third Amended and Restated Credit Agreement at any time, without penalty, subject to certain notice requirements. The loans and other obligations under the credit facility are (a) guaranteed by each of the Company's wholly-owned material domestic restricted subsidiaries, subject to certain exceptions, and (b) are secured by substantially all of the assets of the Company and the subsidiary guarantors, including a pledge of all the capital stock of material subsidiaries held directly by the Company and the subsidiary guarantors (which pledge, in the case of any foreign subsidiary, is limited to 65% of the voting stock), subject to certain customary exceptions and limitations. The Third Amended and Restated Credit Agreement generally prohibits any other liens on the assets of the Company and its restricted subsidiaries, subject to certain exceptions as described in the Third Amended and Restated Credit Agreement. The Third Amended and Restated Credit Agreement contains certain covenants applicable to the Company and its restricted subsidiaries, including, without limitation, limitations on additional indebtedness, liens, various fundamental changes, dividends and distributions, investments (including acquisitions), transactions with affiliates, asset sales, including sale-leaseback transactions, speculative hedge agreements, payment of junior financing, changes in business and other limitations customary in senior secured credit facilities. The Third Amended and Restated Credit Agreement provides for certain baskets that are available to the Company and its restricted subsidiaries to incur additional indebtedness, to repay junior financing, for asset sales and to make investments and restricted payments. Such baskets are substantially similar to the baskets set forth in the Company’s previous amended credit agreement. The Third Amended and Restated Credit Agreement requires the Company to maintain a certain consolidated net leverage ratio. The Company's consolidated net leverage ratio is the ratio of its Consolidated Total Debt minus the lesser of unrestricted cash and 125% of adjusted consolidated EBITDA compared to its adjusted consolidated EBITDA. The Company's maximum consolidated net leverage ratio is 4.00 to 1.00. These covenants and limitations are more fully described in the Third Amended and Restated Credit Agreement. At December 31, 2024, the Company was in compliance with all covenants, including the specified total consolidated net leverage ratio range of 4.00 to 1.00. The Third Amended and Restated Credit Agreement provides that events of default will exist in certain circumstances, including failure to make payment of principal or interest on the loans when required, failure to perform certain obligations under the Third Amended and Restated Credit Agreement and related documents, defaults under certain other indebtedness, certain insolvency events, certain events arising under ERISA, a change of control and certain other events. Upon an event of default, the administrative agent may, or at the request of the holders of more than 50% in principal amount of the loans and commitments shall, terminate the commitments and accelerate the maturity of the loans and enforce certain other remedies under the Third Amended and Restated Credit Agreement and the other loan documents. The Company had unamortized capitalized debt issuance costs, net of $3.1 million at December 31, 2024, which are being amortized over the life of the revolving credit facility. The unamortized capitalized debt issuance costs balance of $0.7 million was included as prepaid expenses and other current assets and a balance of $2.4 million was included as other assets in the Company's consolidated balance sheet at December 31, 2024.
